We honor Dr. Hans L. Falk (1919 -1985) this Earth Day (April 22, but celebrated today, April 23, at NIH) for his significant contributions to the field of environmental health science as both a scientist and an administrator.

Ever since the discovery of the double-helix structure of DNA, scientists have sought ways to edit the genome. Altering gene expression partially and transiently via small interfering RNA has come a long way, and the progress has been spectacular. However, achieving complete and sustained modification of gene expression in a cell remains a tedious procedure that is often costly and time-consuming. For molecular biologists working with cell lines, quick and efficient knock out of one or more genes would provide a powerful tool for their studies. The CRISPR technology arrived two years ago to potentially fulfill that need.

Countries that grow poppies used to hold a monopoly on the ingredients to the main opiate painkilling drugs. Then in 1979, Dr. Kenner Rice of NIDDK’s Laboratory of Medicinal Chemistry (he is now at NIDA) discovered the critical chemical reaction enabling large-scale production of totally synthetic morphine, codeine, and thebaine, the three basic raw materials in opium.

Welcome to LabTV! If you haven’t already, take a look at this video. I hope you will enjoy meeting the first young scientist featured in this brand new series that I’ve chosen to highlight on my blog. The inspiration for LabTV comes from Jay Walker, who is the founder of PriceLine, and curator and chairman of TEDMED, an annual conference focused on new ideas in health and medicine.

Monitoring cell movement. Examining the microenvironment of a tumor. Mapping a gene. Scientists at the NCI Center for Cancer Research (CCR)—the intramural research program at the National Cancer Institute—use a wide variety of microscopy techniques to observe and probe the otherwise invisible processes that drive cancer at the molecular level.

The cover is stained, the binding is broken, and the edges are burnt from use at a laboratory bench. Practical Pathology by Sir German Sims Woodhead, 3rd ed., 1892, belonged in the library of the original Hygienic Laboratory, which became the NIH in 1930. Although it has seen hard use in its 123 years, this book is now in the NIH Stetten Museum collection and begins a month showcasing some of our recent accessions.

Postdocs help power aging research. They receive NIA funding for training. They work with and for NIA grantees. In-house at NIA, they are a critical component of research conducted in NIA labs, which we call “intramural” research. Across the research community, postdoctoral research fellows contribute the long hours necessary to organize and implement research activities. I know this because I am one of them, and colleagues, I see how hard you work!

Choosing to study biology in college was an easy decision for me. Deciding what I would do after college was a little more difficult. Sometimes I think back and wonder: How did I get here?

The winning entry from the 2014 “In Focus! Safe Workplaces for All” photo contest is entitled “Biospecimen Inventory." It not only highlights the importance of proper gear, but also that of maintaining an accurate and up-to-date inventory of biospecimens.

In 2007, the NIH Clinical Center (CC) established two research nursing roles that are critical to the success of the many studies undertaken at the CC. Clinical Research Nurses (CRN) are staff nurses who focus on caring for research participants, while also providing support for studies in a clinical delivery setting. Research Nurse Coordinators (RCN) are responsible for managing research studies and enormous amounts of data collection. They are in charge of recruiting and enrolling participants, maintaining study consistency, and overseeing regulatory adherence.
